GILBERT GIBSON, OF PORT RICHMOND, NFV YORK.

IMPROVED ANCHOR-TRIPPER.

Specification forming part of Letters Patent No. 51,305. dated December5, 1865.

To all whom fit 'may concern:

Be it known that I, GILBERT GIBSON, of Port Richmond, in the county ot'Richmond and State of New York, have invented. a new and usei'ulImproved Anehor-Heaver; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable othersskilled in the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specification.

The object ot the presentl invention is not only to facilitate theheaving ot' an anchor, but to enable it to be accomplished with butlittle trouble, delay, or labor; and it consists in so formingorarranging upon the upper edge and inner sidcof the bulwarksof avessel, and at or near the bow, a resting surface or support for theIiuke ofthe anchor, that, when desired, by simply releasing orunfastening the said support, the anchor will readily t'all and drop byits own weight.

In accompanying plate of drawings my improved anchor-heaver isillustrated in connection with an anchor and one side of the bow portionof a vessel, Figure l being a plan or top view of the same, showing theanchoruke at rest upon the heaving device; and Fig. 2 a partialsectional View taken in a plane across the length of the vessel.

a et in the drawings represent aportion of the deck ot' a vessel at ornear its bow; b, the cat-head, over which the cat-rope c passes and onwhich is hun g the anchor d; j', myimproved anehor-heaver, made of anangular shape, having two arms, g and h, one, g, a considerable longerthan the other, h, the longer one extending along and down upon theinner side,

l, of the bulwarks m., and the other over the upper edge, n, ot' thesame, the beaver turning upon a fulcrum, o, of the top edge, n, andsecured by a swinging lever-handled), of the bul warks, properly andsuitably arranged therefor.

The upper surface ofthe short arm h of the beaver is made with a groove,q, or concave for its whole length, or nearly so, and has a notch,inwhich tits theinner corner, s, of the anchor-tluke t when swung orraised up upon the same,`as represented in the drawings. This beaver j',arranged substantially in the manner described, when secured or held inposition by the holding-lever 19, serves as the rest or support t'or theanchor-fluke, and is to be made of such a form that when the lever p isswung in the proper direction to release the same the weight of theanchor alone and by itselt' will canse it to turn sutlciently todisengage its fluke therefrom, and thus allow it to i'all, as it isevident without further explanation.

W hat I claim as new, and desire to secure by Letters Patent, is-

The combination of' the grooved land bent lever g h q anddetaining-lever p, when constructed and arranged to operate as specied.

The above specification ot' my invention signed by lne this 29th day ot'June, 1865.

GILBERT GIBSON.
